Nervous system 1

2. NT associated with pain, stress, anxiety
4. time membrane is depolarizing; no stimulus
6. gaps between myelin sheaths
8. NT in CNS that is used in sensory perception, mood regulation, & helps in sleeping
11. NT that regulates muscle tone
12. axon cover that increases speed of impulse
13. regulates the ANS within the diencephalon
15. Nervous system division that is voluntary
16. protective involuntary;predictable response
17. fascia surrounding a nerve fiber
19. neuroglia in PNS that make myelin sheaths
22. impulse conducting cell
23. NT used in muscle contraction
26. cerebral area that receives info about proprioception & taste
27. Transmits sensory info toward the CNS
28. "fight or flight" nervous system division
29. bundles of nerve fibers in the CNS
31. cerebral area that house olfactory & Wernicke area
34. area of brain coordinating muscle movements & helps maintain balance & posture
35. area of brainstem that connects the cerebellum & cerebrum with the spinal cord
36. largest superior part of brain
37. largest portion of diencephalon
38. grooves in cerebrum
39. when movement of sodium rushes into cell
40. gap between neuron and following neuron
41. filter that prevents chemicals, viruses, or other harmful substances between the blood and nerve tissue

1. cells support protect, nourish, insulate neurons
3. most inferior part of brainstem; contains respiratory, cardiovascular, & vasomotor centers
5. mechanism that produces & maintains polarization
7. reabsorption of neurotransmitter
9. outer layer of meninges
10. center of brain containing thalamus, hypothalamus, pituitary & pineal gland
14. connective tissue that lines the skull/vertebral column
18. Transmit impulse from CNS to muscles/glands
20. type of conduction along unmyelinated axons
21. receives stimulus; transmits to cell body
24. clear fluid around brain, spinal cord
25. lobe receives info about proprioception
30. joins the right & left sides of cerebrum
32. the study of nervous system
33. resting state of neuron
